TEXTILE SLEEVE HAVING A LOW MELT ADHESIVE COATING WITH PROTECTIVE LAYER THEREOVER AND METHOD OF CONSTRUCTION THEREOF
A protective textile sleeve for providing protection to an elongate member contained therein and method of construction thereof is provided. The sleeve has a wrappable wall including a heat-activatable adhesive disposed thereon. A UV cured layer is disposed over the heat-activatable adhesive to sandwich the heat-activatable adhesive between the wall and the UV cured layer. The UV cured layer prevents the underlying heat-activatable adhesive from adhering to another surface until a suitable heat source activates the heat-activatable adhesive.
1 . A protective textile sleeve for providing protection to an elongate member contained therein, comprising:
a wall of interlaced yarn, said wall having opposite sides extending lengthwise between open opposite ends, said wall having outer and inner surfaces, said inner surface being configured to bound a circumferentially enclosed cavity extending between said open opposite ends;
a heat-activatable adhesive coating bonded to at least a portion of at least one of said outer surface and said inner surface; and
a UV cured, non-adhesive layer disposed on said heat-activatable adhesive coating to sandwich said heat-activatable adhesive coating between said wall and said UV cured, non-adhesive layer, said UV cured, non-adhesive layer preventing said heat-activatable adhesive coating from adhering to other portions of said wall absent application of a heat source suitable to melt said heat-activatable adhesive coating.
2 . The protective textile sleeve of claim 1 wherein said heat-activatable adhesive coating is bonded to at least a portion of said inner surface of said wall.
3 . The protective textile sleeve of claim 2 wherein said heat-activatable adhesive coating is bonded to said inner surface along at least one of said opposite sides.
4 . The protective textile sleeve of claim 3 wherein said heat-activatable adhesive coating extends substantially from one of said opposite ends substantially to the other of said opposite ends.
5 . The protective textile sleeve of claim 3 wherein said heat-activatable adhesive coating is bonded to said inner surface along each of said opposite sides.
6 . The protective textile sleeve of claim 5 wherein an intermediate portion of said inner surface, between said opposite sides, is free of said heat-activatable adhesive coating.
7 . The protective textile sleeve of claim 5 wherein said heat-activatable adhesive coating is bonded to a substantial entirety of said inner surface.
8 . The protective textile sleeve of claim 1 wherein said wall is heat-set with said opposite sides being biased into overlapping relation with one another.
9 . The protective textile sleeve of claim 1 wherein said heat-activatable adhesive coating is between about 0.2-0.4 mm thick and said UV cured, non-adhesive layer is between about 0.01-0.05 mm thick.
10 . A method of constructing a textile protective sleeve, including:
interlacing yarn to form a wall having an inner surface and an outer surface extending between opposite ends;
bonding a heat-activatable adhesive coating to at least a portion of at least one said inner and said outer surfaces;
applying a UV curable, non-adhesive layer on said heat-activatable adhesive coating to sandwich said heat-activatable adhesive coating between said wall and said UV cured, non-adhesive layer; and
curing said UV curable, non-adhesive layer to prevent said heat-activatable adhesive coating from adhering to other portions of said wall absent application of a heat source suitable to melt said heat-activatable adhesive coating.
11 . The method of claim 10 , further including bonding said heat-activatable adhesive coating to at least a portion of said inner surface of said wall.
12 . The method of claim 11 , further including bonding said heat-activatable adhesive coating to said inner surface along at least one of said opposite sides.
13 . The method of claim 12 , further including bonding said heat-activatable adhesive coating to extend substantially from one of said opposite ends substantially to the other of said opposite ends.
14 . The method of claim 12 , further including bonding said heat-activatable adhesive coating to said inner surface along each of said opposite sides.
15 . The method of claim 14 , further including leaving an intermediate portion of said inner surface extending between said opposite sides free of said heat-activatable adhesive coating.
16 . The method of claim 14 , further including bonding said heat-activatable adhesive coating to a substantial entirety of said inner surface.
17 . The method of claim 10 , further including heat-setting said wall to bias said opposite sides into overlapping relation with one another.
18 . The method of claim 17 , further including heat-setting said wall prior to bonding said heat-activatable adhesive coating to said wall.
19 . The method of claim 10 , further including applying said heat-activatable adhesive coating having a thickness between about 0.2-0.4 mm and applying said UV cured, non-adhesive layer having a thickness between about 0.01-0.05 mm.
20 . A protective textile sleeve for providing protection to an elongate member contained therein, consisting of:
a wall of interlaced yarn, said wall having opposite sides extending lengthwise between opposite ends, said wall having outer and inner surfaces, said inner surface being configured to bound a circumferentially enclosed cavity extending between open opposite ends;
a heat-activatable adhesive coating bonded to at least a portion of at least one of said outer surface and said inner surface; and
a UV cured, non-adhesive layer disposed on said heat-activatable adhesive coating to sandwich said heat-activatable adhesive coating between said wall and said UV cured, non-adhesive layer, said UV cured, non-adhesive layer preventing said heat-activatable adhesive coating from adhering to other portions of said wall absent application of a heat source suitable to melt said heat-activatable adhesive coating.
